My Project Struct

When I run command docker compose up --build I get error as the below, I felt something wrong when docker try to mount or read something from db directory but how to fix it?

Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/run/desktop/mnt/host/e/Codes/docker-practice/docker-nodejs-sample/db/password.txt" to rootfs at "/run/secrets/db-password": mount /run/desktop/mnt/host/e/Codes/docker-practice/docker-nodejs-sample/db/password.txt:/run/secrets/db-password (via /proc/self/fd/6), flags: 0x5000: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

Thanks for sharing the issue.

Unfortunately, this looks like it may be a system-specific configuration issue.
For help troubleshooting, you can try the community Slack at https://join.slack.com/t/dockercommunity/shared_invite/zt-1jz09gjit-P2NPysg99kiWExFfof0oBA

You can try running a simple container that bind mounts that file in order to see if it fails.
For example:
docker run --rm -v "E:\Codes\docker-practice\docker-nodejs-sample\db\password.txt:/test-password.txt" alpine cat /test-password.txt

That'll run a alpine container, bind mount your password.txt file inside it, and then print out the password contained inside.

If you want to do a workaround and troubleshoot later, you can avoid using secrets.
For example:

services:
  server:
    build:
      context: .
    environment:
      NODE_ENV: production
      POSTGRES_HOST: db
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: mysecretpassword
      POSTGRES_DB: example
    ports:
      - 3000:3000

    depends_on:
      db:
        condition: service_healthy
  db:
    image: postgres
    restart: always
    user: postgres
    volumes:
      - db-data:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=example
      - POSTGRES_PASSWORD=mysecretpassword
    expose:
      - 5432
    healthcheck:
      test: ["CMD", "pg_isready"]
      interval: 10s
      timeout: 5s
      retries: 5
volumes:
  db-data:

For the above example, you can learn about the environment variables used at https://hub.docker.com/_/postgres and in the src/persistence/postgres.js file.

Thank for replying to me, I have no idea what happened, but today I'm tried remove postgresql image and re-pull it. After that, I ran docker cmd again, and it work for me without change anything in the compose file.
